OVEN FLUE OUTLET Filed April 5. 1930 I Patented Oct. 20, 1931 PATENTOFFICE UNITED STATES LESTER s., murmur, or an. LOUIS, mssouanassienoaromnalcan 'srovn conrm, or sun. Louis, mssoum. A ooaronarrqn or new manyI l ovmr Fl t E 6am Application filed April 8,

This invention relates to improvements in oven flue outlets,particularly or use in con nection with gas ranges and might be termed afluev gas deflector, as the purpose of the 3 device is to deflect theflue gases-which escape from the oven in a forwardly direct on toprotect the kitchen walls from being marred by these gases where theflue outlet of the oven is not connected with a flue pipe. At thepresent time, it is quite a common practice to allow the flue gases fromthe oven of the gas range to escape into the kitchen rather tl'ian toconnect the oven outlet with a flue pipe leadin "to a point outside ofthe house, and it has een the common practlce to let these flue gasesescape in a vertical direction with the result that the kitchen wallsbecome stained andom'arred from the passage of the oven gases along thesurface of the walls.

The present invention has been conceived to overcome this objection.which is-present in the flue constructionsc'ommonly used and the presentinvention has "also been conceived so as to provide a flue gas outlet ordeflector which is more pleasing in appearance than those now known andin use and, additionally, to rovi de a device which is readily and quic1y attachableto the oven of the range in a simple manner.

Accordingly, the primary, object of the invention is the provision of anovel oven flue outlet or oven flue gas deflector.

A further object of the inventionv is the scribed which is pleasing inappearance.

A still further object of the invention is the provision of a device ofthe character'- provision of a device of. the character de-.

attachable mo. an to; 441,290.

in conjunction with the accompanying drawm s.

n the drawings: Figure 1 is a view in front elevation of a .range ovenhaving attached thereto the improved oven outlet flue.

Figure 2 is a fragmentary vertical sectional view through the upper rearend of a range oven showing the attachment of the improved flue outlet.v

In its preferred form, the outlet flue or deflector is made in threepieces, two of which are sheet-metal stampings, while one is a castqing. The sheet metal stampings are indicated at A and B, and the castingat C.

The oven as an entiretyisv designated at D. The oven shown is one ofmore-or-less conventional type in that the oven top l'has at its rearedge a depending flange 2, which tele-' scopes or receives behind it theupper edge 1) of the'rear oven wall 4, which wall is pro-,

vided with an outlet opening 5 in connection with the flue arrangement 6of the'interior of the oven.

The stamping A is adished oval shaped member-having at its open'side aperipheral outwardly bent flange 7, which flange at the bottom of the,member is provided with an;

elongated depressed or .dished extension '8 .having therein an opening9.

The stamping or memberB, at its" bottom,

presents an elongated straight line flatportion 10. Centrally of themember it is provided with a depressed portion 11 forming thevperipheral edge of an opening 12, with the result that the depressedportion. 11 "is surrounded by a U-shaped bulge 13.

c The casting-C is of circular form and of a diameter to properly fitwithin the depressed portion 11 of the member B, and as it; is pro-"videdlwith a plurality of openings 14, this casting constitutes a gridfor the enlarged opening 12 of the ring B. Centrally of its rear face,the casting or grid 0 is provided with a lug 15, having an interiorlyscrewthreaded opening 16.

The ring B and the grid C are secured to the upper end of the ovaldished shaped member A, by means of a long bolt 17, which passes throughthe rear of the back wall 18. of the member A and is threaded into thelug 15, of the grid. The rear wall 18 of the member A is formed with thede ression 19 to receive the head 20 of the securing bolt 17.

Intermediate of its length, the flange 7 of the deflector member A isprovided with two tongues 21, which are ofi'set from the flange andextend in vertical parallel relation in respect thereto.-

The member A is attached to the oven by inserting the tongues 21upwardly between the depending flange 2 of the oven top and the upperedge 3 of the rear wall of the oven am then securing the bottom of themember A to the re'arwall of the oven by means of a bolt 22 and the nut23. It will be seen that the bolt 22 always remains in place by reasonof thelock nut 24, which look nut is received within the dished portionof the flange extension 8.

lVith the parts secured and positioned as above described, it will beseen that the bulged portion 13, rests upon the oven top at its rearedge with the elongated portion 10 of the ring 13 paralleling andengaging'the outer surface of the depending flange 2 of the oven top,thus aiding in the support of the entire device.

VVit-h the device secured in-the manner described, the flue outlet5 inthe rear wall of the oven is in communication with the interior of thedished oval shaped deflector and conveyor A, and the conve or A isclosed throughout thegreater portion of its length by the rear Wall ofthe oven to form in conjunction therewith a pipe.

It will be further seen that as the flue gases pass up the conve or,they will be discharged forwardly throug the grid 0 enings 14, over the,oven top, and thus directe away from the walls of the kitchen.

The device is very simple and cheap of construction and is made in onlythree parts and furthermore, it is quickl and easily assembled andattached to t e oven range.

When the deflector is in place, it is held securely against displacementand provides an eflicient oven flue and oven flue gas defleet-or. Byreason of the bulge 13, the stam ing or annular ring B is supportedthrong out its length upon the rear edge of the oven laving thusdescribed m invention what I claim and desire to secure y Letters Patent18:

i A range having a flue ,outlet in its rear vertical wall, of an outsideflue having its inner side flat vertically and fitting against the saidrear vertical wall of-the range subsignature.
